Prerequisites

• I have searched existing issues and discussions to ensure this feature hasn't been requested before
• I have read the feature request guidelines in the README
• I understand that MeTube development relies on community contributions and the maintainer is not likely to implement this feature
• I have considered if this feature should be implemented in yt-dlp instead of MeTube (if so, please report to yt-dlp repository)

Feature Description

Currently there is no way to stop the automatic parsing and addition of playlist entries once started (say, if someone intended to add a single video but linked to the playlist, each successive video is added).

It would be very nice to have a button to stop the processor from seeking out more entries.

Implementation Plan

No, I'm requesting this feature but cannot implement it
